.SHORT TERM... (Today and tonight) Issued at 1203 AM CDT Mon Sep 15 2025
The stubborn showers and thunderstorms from earlier in and around Childress have finally moved out of the area as a mid level trough departs to the north and east. Another line of storms is currently tracking southward across the eastern Panhandle and may clip this same area in the next few hours. Otherwise, a quiet night is expected in the wake of the trough with partly clear skies, light winds, and lows ranging from the upper 50s over the far SW Panhandle to the low-to-mid 60s elsewhere. Given the residual moisture from Sunday and an approaching ridge, patchy fog remains possible around sunrise, mainly on the Caprock. This should quickly burn off and a mostly pleasant day is expected as the aforementioned ridge builds. Mostly sunny skies and highs near seasonal average in the mid-to- upper 80s are likely. CAMs continue to indicate some isolated convection developing in the afternoon/evening. However, there is an absence of notable features providing anything in the way of forcing. Dewpoints will remain in the 60s, so this moisture combined with daytime instability may lead to the development of a rogue cell or two and some mentionable PoPs have been retained. Nonetheless, the overall synoptic pattern is not particularly supportive of driving any thunderstorm activity. Quiet conditions will continue into Tuesday morning, with similar low temperatures as this morning.

.LONG TERM... (Tuesday through Sunday) Issued at 1203 AM CDT Mon Sep 15 2025
Weak upper flow will persist on Tuesday and bring little change from Monday. A complex upper flow pattern will begin to create forecasting challenges beginning Tuesday afternoon. A trough will begin to descend over the Mountain West and a shortwave will track across the Panhandle during the afternoon/evening hours. Nothing else is terribly anomalous. The latest NAM does indicate some semblance of a low-level jet clipping the far SW Panhandle, putting it in the right entrance region, but this area would be upstream of the weak vort lobes from the aforementioned shortwave. In any case, like Monday, some mentionable PoPs have been retained, but any storms that develop would be very isolated.
An upper low will become cutoff from its parent trough early Wednesday over the Canadian Prairies and lead to an almost Fujiwara like effect with the more broad trough now centered over the Dakotas. As this occurs it will push an initial shortwave over the Panhandle, leading again to possible afternoon/evening showers and thunderstorms over the far southern Panhandle. As the two lows merge on Thursday, the overall trough axis will approach from the northwest and bring the best storm chances of the week across the entire area. Broad chance PoPs will be continued in the latest forecast given the complexity of the upper pattern to the north. Things could certainly change significantly between now and then. A relatively strong ridge looks to build Friday into the weekend, however embedded waves may continue to bring the usual late-day storm chances.

.AVIATION... (12Z TAFS) Issued at 612 AM CDT Mon Sep 15 2025
Very patchy fog was lingering around the area early this morning which may affect KLBB or KPVW but the limited coverage does not warrant a mention in the TAF. A thunderstorm outflow boundary was also sagging into the area which has resulted in light and variable winds at KCDS and KPVW. There is a small chance of isolated thunderstorms this afternoon at all TAF sites.
